Extra rings that never rust, warp, or wear out.
Vertical ridges make them easy to grip and twist on or off, even with wet or slippery hands, and because they're plastic instead of metal, they'll never rust in the dishwasher or freezer — the easiest way to keep a spare ring in rotation for every jar in the house.

Nice to have some extras on hand
These work great and it's nice to have some extras on hand. We've broken a couple after some drops on hard floors with full water bottles, but they usually hold up really well. Nice to have the flexibility to easily attach a lid for on the go.

I kinda thought I wouldn't need this since I have a ton of the metal ones, but these work so much better. They have a way better seal for preventing leaks!

Must have!
The rings fit on all my mason jars at home. I love the versatility!
